WATER-GAGE.

Specicaton of Letters Patent.

Patented May 4, 1915.

Application iled February 4, 1913. Serial No. 746,159.

T0 all whom it may concern Be it known that I, WILLIAM F. GREEN, acitizen of the United States, residing at Modesto, in the county7 ofStanislaus and State ,of California, have invented certain new anduseful Improvements in Water- Gages, of which the following is aspecifica-- tion.

The object of my invention is to indicateA or set into action uponactuation of the day signal.

The device of my invention will be more fully Idescribed in connectionwith` the accompanying drawing, and will be more particularly pointedout in and by the appended claim.

In the drawing :-Figure 1 is a view of a radiator and the device of myinvention viewed from the drivers seat, the parts being shown inelevation. Fig. 2 isa similar view with the parts shown in section. Fig.3 is a horizontal sectional view on line 3-3 of Fig. 1.` Like charactersof reference designate similar parts throughout thedifferent figures ofthe drawing.

As shown, 1 designates a radiator tankl having an opening 2 adapted tobe closed by a top or cap 3.

Mounted in the cap 3 is a shield support, preferably tubular in form, asindicated at 4. Shields 5 and 6 are mounted on said support and arepreferably trapezodial in form. The shields 5 and 6 are disposed inspaced relation with respect to each other and may be connected bypivots 7 and 8, in the form of rivets. Within the support 4, is mounteda guide, preferably in the form of a tube 9, which may extend upwardlybetween the shields 5 and 6, and above the same, and which may beprovided with a suitable ornamental top 10. Theguide tube 9 may beslotted at 11 and an actuator bar 12, having mal position.

ends guided in said slots 11, may be disposed in said guide tube, asindicated in Fig. 2.

Signal elements, preferably in the forni of blades 13 and 14, arepivotally mounted at 7 and 8 and are Aadapted to normally lie betweenthe shields 5 and (i So as to be invisible tothe occupants of the calwhen in a nor- The signal blades 13 and 14 may be provided with a colorarrangement such as would graphically distinguish them from the color ofthe shield 5.

The upper ends of the blades 13 and 14 are rounded, as -at 15 and 16,and said rounded ends are disposed in overlapping relation with respectto each other, and are of such proportions as to lie in overlappingrelation with respect to each other, even when in their normal position.It will also be seen that the overlapping ends of the blades 13 and 14are disposed inwardly with respect to the vpivots 7 and 8 on which theyare mounted. The actuating bar 12 is adapted for engagement with therounded ends 15 and 16 o f the blades 13 and 14 so as to expand the sameoutwardly from the shields 5 and 6, as indicated in dotted lines in Fig.1 and in full lines in Fig. 2, when the actuator bar 12 is moveddownwardly' in the guide tube 9. The actuator bar 12 is provided withconnections, which may be in the form of flexible wires 17, with a floatsoy 18, disposedin the radiator tank 1. When the water in the tank 1becomes depleted, and the level sinks, the weight of the float 18 willbe sufficient to exert enough pressure on the actuator bar 12 toovercome friction of movement of the parts, and spread the signal blades1 3 and 14 as indicated in Fig. 2. An indicator rod 19 extends throughan inserted centrally disposed conical open portion 20, of the float 18,and upwardly in the guide tube 9 wherein it is provided with an enlargedhead 21. The guide tube 9 is provided with an opening 22, having agraduated margin' 23, abreast of which an index or pointer 24, moves. Bymeans of this arrangement, the driver can at all times determine thewater level.

In the event that darkness or fog might prevent the blades 13 and 14from being seen by the driver, I may provide an electric signal which ispreferably cut into and out of circuit by the blades 13 and 14, or onethereof.

As illustrated, an incandescent lamp 25 is mounted upon the guide tube 9in a socket 26. One pole of the lamp is connected by a Wire 27, with asource of supply of current 28, which latter is grounded through theframe of the machine. The other pole of the lamp is connected by acontact 29 with a Wire 30, the latter being insulated from the signalframe and having a terminal end 3l lying in the path of the blade 14. Asecond contact 32, also lies in the path of the blade 14 and is groundedon the frame. It will thus be seen that when the signal blades orelements 13 and 14 are spread, as indicated in Fig. 2, circuit will beclosed so as to cause the electric lamp 25 to glow.

While I have herein shown and described one specific form of myinvention, I do not Wish to be limited thereto except for suchlimitations as the claim may import.

I claim The combination with an automobile tank having a fillingaperture, of a cover for said lling aperture, a water level signalmountbeing adapted to normally be concealed by said shields, anactuating bar extending through the slots in the vertical tubularfmember and in operative engagement with the said pivoted signal blades,a float disposed in said tank, a vertical rod carried by said float, andflexible members connecting. the upper end of said rod with saidactuating bar whereby the signal blades are moved into their extendedposition.

In testimony whereof I'alix my signature in presence of two witnesses.

WILLIAM F. GREEN.
